or) said, ‘He-asws was asked about the man when the sun declines (midday) and he is in his house, then he goes out in a journey. He-asws said: ‘He should begin with the midday. He should pray it, then pray the foremost (Al-Zohr) with shortening, as two Cycles, because he had gone out from his house before the foremost had presented’. And he-asws was asked, ‘Supposing he goes out after the foremost (Al-Zohr) had presented? ’
He-asws said: ‘He should pray the foremost (Al-Zohr) as four Cycle, then pray the optional eight Cycles afterwards, because he had gone out from his house after the foremost (Al-Zohr) had presented’’. [27]
And from Bashir Al Nabbal having said (in Al Tahzeeb), ‘I went out with Abu Abdullah-asws until we came to a tree. Abu Abdullah-asws said to me: ‘O Nabbal! ’ I said, ‘At your-asws service! ’
He-asws said: ‘Surely it is not obligated upon anyone from the people of this encampment to pray four (Cycles) apart from me-asws and you, and that is because the time of Salat had entered before we had gone out’’. [28]
And it is supported regarding the return a correct (Hadeeth) by Mansour (in Al Tahzeeb) who said, ‘I heard Abu Abdullah-asws saying: ‘When he was in a journey and the time of a Salat enters unto him before he enters to his family, so he travels until he enters to his family, if he desires, he can shorten (Salat) and if he desires, he can pray complete, and the complete is more beloved to me’’. [29]
And it is supported by what is reported in the trusted (Hadeeth in Al Tahzeeb), from Is’haq Bin Ammar who said, ‘I heard Abu Al-Hassan-asws saying regarding the man arriving from his journey during the time of a Salat. He-asws said: ‘If had not feared the missing out, let him pray complete, and if he had fear the lapsing of the time, let him shorten’’. [30]
